Flume代理不包含任何有效渠道

Question

我是 Flume 的新手。我试图从 Twitter 中提取数据，但没有成功。（我正在使用 Cloudera Quickstart）

我的配置文件如下所示：

TwitterAgent.sources = Twitter
TwitterAgent.channels = MemChannel
TwitterAgent.sinks = HDFS

TwitterAgent.sources.Twitter.type = com.cloudera.flume.source.TwitterSource
TwitterAgent.sources.Twitter.channels = MemChannel

我已经添加了所有这些取自 Twitter 帐户 consumerKey、consumerSecret、accessToken、accessTokenSecret、关键字和路径的值

TwitterAgent.sinks.HDFS.channel = MemChannel
TwitterAgent.sinks.HDFS.type = hdfs
TwitterAgent.sinks.HDFS.hdfs.fileType =  DataStream
TwitterAgent.sinks.HDFS.hdfs.writeFormat = Text
TwitterAgent.sinks.HDFS.hdfs.batchSize = 1000
TwitterAgent.sinks.HDFS.hdfs.rollsize = 0
TwitterAgent.sinks.HDFS.hdfs.rollCount = 10000

我用来执行 conf 文件的命令是：

flume-ng agent --conf conf --conf-file flume.conf -Dflume.root.logger=DEBUG,console -name TwitterAgent

我得到的错误是：

18/06/27 12:17:18 WARN conf.FlumeConfiguration: Agent configuration for 'TwitterAgent' does not contain any valid channels. Marking it as invalid.
18/06/27 12:17:18 WARN conf.FlumeConfiguration: Agent configuration invalid for agent 'TwitterAgent'. It will be removed.
18/06/27 12:17:18 INFO conf.FlumeConfiguration: Post-validation flume configuration contains configuration for agents: []
18/06/27 12:17:18 WARN node.AbstractConfigurationProvider: No configuration found for this host:TwitterAgent
18/06/27 12:17:18 INFO node.Application: Starting new configuration:{ sourceRunners:{} sinkRunners:{} channels:{} }

请多多指教

我认为你的执行命令有问题，错误是关于查找配置文件。

命令应该是

flume-ng agent -c conf -f conf/flume.conf -Dflume.root.logger=DEBUG,console -n TwitterAgent

您必须指定您的配置文件路径。您可以尝试 -f conf/flume.conf 而不是 -f flume.conf
